KeepYourChildsFluorideIntakeataSafebutEffectiveLevel

Fluoride is an important part of your child's dental development. But if children take in too much of this important mineral, they could experience enamel fluorosis, a condition in which teeth become discolored with dark streaking or mottling.

That's why it's important to keep fluoride levels within safe bounds, especially for children under the age of 9. To do that, here's a look at the most common sources for fluoride your child may take in and how you can moderate them.

Toothpaste. Fluoridated toothpaste is an effective way for your child to receive the benefits of fluoride. But to make sure they're not getting too much, apply only a smear of toothpaste to the brush for infants. When they get a little older you can increase that to a pea-sized amount on the end of the brush. You should also train your child not to swallow toothpaste.

Drinking water. Most water systems add tiny amounts of fluoride to drinking water. To find out how much your water provider adds visit “My Water's Fluoride” (//nccd.cdc.gov/doh_mwf/Default/Default.aspx) online. If it's more than the government's recommendation of 0.70 parts of fluoride per million parts of water, you may want ask your dentist if you should limit your child's consumption of fluoridated drinking water.

Infant formula. Many parents choose bottle-feeding their baby with infant formula rather than breastfeed. If you use the powdered form and mix it with tap water that's fluoridated, your baby could be ingesting more of the mineral. If breastfeeding isn't an option, try using the premixed formula, which normally contains lower levels of fluoride. If you use powdered formula, mix it with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”

It might seem like the better strategy for preventing fluorosis is to avoid fluoride altogether. But that can increase the risk of tooth decay, a far more destructive outcome for your child's teeth than the appearance problems caused by fluorosis. The better way is to consult with your dentist on keeping your child's intake within recognized limits to safely receive fluoride's benefits of stronger, healthier teeth.

KeepaCloseEyeonYourChildsFluorideIntake

Fluoride has been proven to strengthen tooth enamel against decay. That’s why it’s not only added to toothpaste and other dental products, but also to drinking water — in nearly three-quarters of U.S. water systems.

While research has eased most serious health questions about fluoride, there remains one moderate concern. Too much fluoride over time, especially in infants and young children, could lead to “enamel fluorosis,” an excess of fluoride in the tooth structure that can cause spotting or streaking in the enamel. While often barely noticeable, some cases of fluorosis can produce dark staining and a pitted appearance. Although not a symptom of disease, fluorosis can create a long-term cosmetic concern for the person.

To minimize its occurrence, children under the age of 9 shouldn’t regularly ingest fluoride above of the recommended level of 0.70 ppm (parts per million). In practical terms, you as a parent should monitor two primary sources of fluoride intake: toothpaste and drinking water.

Young children tend to swallow toothpaste rather than spit it out after brushing, which could result in too much fluoride ingestion if the amount is too great. The American Academy of Pediatric Dentistry therefore recommends a small “smear” of toothpaste for children under two, and a pea-sized amount for children up to age six. Brushing should also be limited to no more than two times a day.

Your child or infant could also take in too much fluoride through fluoridated drinking water, especially if you’re using it to mix infant formula. You should first find out the fluoride levels in your local water system by contacting the utility or the health department. If your system is part of the U.S. Centers for Disease Control and Prevention’s (CDC) “My Water’s Fluoride” program, you may be able to access that information on line at //apps.nccd.cdc.gov/MWF/Index.asp.

If the risk for developing fluorosis in your area is high, you can minimize your infant’s intake with a few recommendations: breastfeed rather than use formula; use “ready-to-feed” formula that doesn’t need mixing and contains lower fluoride levels; and use bottled water specifically labeled “de-ionized,” “purified,” “de-mineralized,” or “distilled.”

Fluoride can be a wonderful adjunct to dental care in reducing risk for tooth decay. Keeping an eye on how much fluoride your child takes in can also minimize the chance of future appearance problems.

TopicalFluorideCouldFurtherLowerToothDecayRiskinChildren

Since the discovery a century ago of its beneficial effect on tooth enamel, fluoride has become an important part of tooth decay prevention. It's routinely added to toothpaste and other hygiene products, and many water utilities add minute amounts of it to their drinking water supplies. Although there have been questions about its safety, multiple studies over the last few decades have eased those concerns.

Children especially benefit from fluoride during their teeth's developing years. Some children are at high risk for decay, especially an aggressive form known as Early Childhood Caries (ECC). ECC can destroy primary (baby) teeth and cause children to lose them prematurely. This can have an adverse effect on incoming permanent teeth, causing them to erupt in the wrong positions creating a bad bite (malocclusion).

For children at high risk for decay, dentists often recommend applying topical fluoride directly to the teeth as added protection against disease. These concentrations of fluoride are much higher than in toothpaste and remain on the teeth for much longer. Topical applications have been shown not only to reduce the risk of new cavities, but to also stop and reverse early decay.

Children usually receive these applications during an office visit after their regular dental cleaning. There are three different ways to apply it: gel, foam or varnish. To prevent swallowing some of the solution (which could induce vomiting, headache or stomach pain) the dentist will often insert a tray similar to a mouth guard to catch any excess solution. Varnishes and a few gels are actually painted on the teeth.

The American Dental Association has intensely studied the use of topical fluoride and found its application can result in substantial decreases in cavities and lost teeth. They've concluded this benefit far outweighs the side effects from ingesting the solution in children six years and older. With proper precautions and waiting to eat for thirty minutes after an application, the possibility of ingestion can be reduced even further.

While topical fluoride can be effective, it's only one part of a good dental care strategy for your child. Consistent daily brushing and flossing, a nutritious diet low in added sugar, and regular dental visits still remain the backbone of preventive care.
